Specifications

This gas analyser is used to measure NO, CO2, CO, CH4, SO2 and O2. NO, CO2, CO, CH4 and SO2 gases are measured by non-dispersive infrared, while O2 is measured by the electrochemical, paramagnetic or zirconia method. It can analyse up to 4 gases plus oxygen simultaneously. For the infrared part, it uses a highly sensitive mass flow meter as detector. The single-beam photometric system ensures simplified maintenance and excellent stability over time. The analyser is particularly well suited to monitoring pollutant emissions.

 

Measurable componentsNO, CO2, CO, CH4, SO2 and O2
Measuring principleNon-dispersive infrared absorption method.
Single source, single beam		NO, SO2, CO2, CO, CH4
Electrochemical or paramagnetic method (measuring element incorporated intoanalyser) or zirconia method (analyser ).O2
Repeatability±0.5% of full scale
Linearity±1% of full scale
Zero drift±2% of full scale/week
Negligible when using automatic zero calibration
